In reviewing a patient’s complete blood count (CBC) results, the nurse notes a "shift to the left." What is the significance of these results?

There is an elevated number of immature thrombocytes.

There is an elevated number of immature neutrophils (bands),

There is an elevated number of mature neutrophils (segs)

There is an elevated number of mature erythrocytes

Answer and Explanation

The Correct Answer is B

A. There is an elevated number of immature thrombocytes - Thrombocytes are platelets, and a shift to the left does not refer to these.

B. There is an elevated number of immature neutrophils (bands) - A "shift to the left" typically refers to an increase in immature neutrophils, also known as bands, in the blood. This often indicates an acute infection or inflammation as the body is producing and releasing more neutrophils to fight an infection.

C. There is an elevated number of mature neutrophils (segs) - An elevated number of mature neutrophils (segmented neutrophils) does not indicate a shift to the left. The term specifically refers to immature forms.

D. There is an elevated number of mature erythrocytes - Mature erythrocytes are red blood cells, and a shift to the left does not pertain to red blood cell counts or maturity.

A. Elevate the limb and apply ice. B. Apply a tourniquet just below the elbow. C. Apply direct pressure over the wound. D. Clean the wound.

Correct Answer is C

Explanation

A. Elevate the limb and apply ice. Elevating the limb and applying ice can help reduce blood flow to the area and minimize swelling. However, it is not the immediate priority in managing active, profuse bleeding.

B. Apply a tourniquet just below the elbow. A tourniquet should be a last resort due to the risk of cutting off blood flow and potential limb damage. It's typically used in life-threatening situations where other methods fail to control bleeding.

C. Apply direct pressure over the wound. The immediate priority for controlling profuse bleeding is to apply direct pressure to the wound to stop or reduce the bleeding. This is a standard first-line intervention in hemorrhage management.

D. Clean the wound. Cleaning the wound is important to prevent infection, but it is not the first priority when dealing with active, profuse bleeding.
